use the system described here for typing directly on a draughting table, a book, notebook or the like by eliminating from a machine similar to the one described here, the carriage and attaching said machine on a suitable frame. In

such a case the machine itself is displaced horizontally and vertically on said frame. WhatIclaim is:

1. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings and having gear sectors individually fixed thereon; pinion sectors rotatably mounted adjacent to the gear sectors, said type levers and gear sectors being movable from an inactive to an initially active position; movable means operable by the keys for bringing said type levers to the initially active position; and spring operated means effective upon operation of said movable means by said keys in the initially active position of said type levers to engage and mesh the pinion sectors with the gear sectors and effeet a typing stroke of the type levers respectively corresponding to the operated keys.

'2. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings and having gear sectors individually fixed thereon remote from the type thereof; a plurality of movable link bars actuated 'by the keys; means upon the type levers cooperating with said link bars in one operated position of the latter for raising said type levers to initially active position and in another position being withdrawn from said operated position and allowing said type levers to occupy an inactive -position; a plurality of pinion sectors rotatably mounted adjacent to the gear sectors; and spring operated means for engaging and meshing the pinion sectors with the gear sectors in the initially active position of the type levers and effective to operate said type leversand provide a typing action thereof upon movement of said link bars from withdrawn to operated position by said keys.

3. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings; a plurality of slidable link bars actuated by the keys; shoulders on the type levers; abutments on the link bars cooperating with the shoulders on the type levers in one position of the link bars to bring said type levers into an initially operative position but disabling the cooperation'between said shoulders and abutments in another position of said link bars and allowing the type levers to recede to inactive position; normally inactive spring operated means efiective in the initially operative position of the type levers to operate said type levers to effect a typing action upon operation of said keys; and means operable upon sliding movement of said link bars caused by operation of said keys for causing said spring operated means to effect a typing action of the type levers respectively corresponding to the operated keys.

4.111 a typewriter; a type leve'r operating mechanism; including a' plurality of' manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings; a plurality of slidable link bars actuated by ,the keys; shoulders on the type levers;

supporting abutments on the link bars cooperating with the shoulders on the type levers for supporting the latter in raised initially operative .position in an advanced operated position of the link bars, the shoulders on said type levers clearing the supporting abutments in a retracted position of said link bars and allowing the type levers to recede to inactive position; normally inactive spring operated'means effective in the initially operative position of the type levers to operate said type levers to effect a typing action upon operation of said keys; and means operable upon sliding movement of said link bars caused by operation of said keys for causing said spring operated means to effect a typing action of the type levers respectively corresponding to the op erated keys. I 7 v 5. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings and havinggear sectors fixed thereon remote from the type thereof; a plurality of slid able link bars actuated by the keys; shoulders'on the type levers; abutments on the link bars no: operating with the shoulders on the type levers in one position of the link bars to bring said type levers into an initially operative position but disabling the cooperation between said shoulders and abutments in another \position of said link bars and allowin the type levers to re cede to inactive position; pinion sectors rotata, bly mounted adjacent to the gear sectors said type levers and effective to engage and mesh therewith in the initially operative position. of said type levers; and spring operated means for engaging and meshing said pinion sectors with said gear sectors in the initially operative posi tion of the type levers to actuate said type levers in order to effect a typing action upon operation of said keys.

6. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings and having gear sectors individually fixed thereon; pinion sectors rotatably mounted adjacent to the gear sectors, said type levers and gear sectors being movable froman inactive to an initially active position; a plurality of lon gitudinally slidable elongated horizontal link bars actuated by the keys; shoulders onf'the typfe levers; corresponding abutments'on the link bars cooperating with the shoulders on the type levers in one position of said link bars to support said type levers in the initially active position and in anotherposition' of said link bars allowing said type levers to occupy an inactive position; and spring operated means efiective 'to meshsa'id pinion sectors with said gear sectors in the ni: tially active position of said type levers and thereby produce a typing stroke.

'7. In a typewriter, a type lever operating mechanism, including a plurality of manually operable keys; a plurality of pivotally mounted type levers freely oscillatable on their pivot mountings and having gear sectors individually fixed thereon; pinion sectors rotatably mounted adjacent to the gear sectors, said type levers and gear sectors being movable from an inactive to an initially active position; a plurality of horizontally movable link bars actuated by the keys; shoulders on the type levers; corresponding abutments on the link bars cooperating with the shoulders on the type levers in one position of said link bars to support said type levers in the initially active position and in another position l of said link bars allowing said type levers to occupy an inactive position; spring operated means efiective to mesh said pinion sectors with .6 said gear sectors in the initially active position of said type levers and thereby produce a typing stroke; and an intermediate rotatably mounted shaft rotatable upon operation of said key and movement of the corresponding link bars and efiective to cause operation of said spring operated means.
